Guide: The boiler is a kind of energy conversion equipment. The energy we input to the boiler is chemical energy and electric energy in the fuel, and then the boiler will output steam with heat energy, high temperature water or organic heat carrier. This series is the working process of the boiler.
First of all, we have to understand, what is a boiler?
The boiler is a kind of energy conversion equipment. The energy we input to the boiler is chemical energy and electric energy in the fuel, and then the boiler will output steam with heat energy, high temperature water or organic heat carrier. This series is the working process of the boiler.
What is boiler energy saving technology?
Boiler energy-saving technology is an organic combination of high-tech material technology, combustion technology and comprehensive boiler technology. After a series of physical and chemical changes, the combustion of coal can achieve enhanced combustion, full combustion, and complete combustion. It can improve the thermal efficiency of the boiler, can make the thermal efficiency of the boiler reach 70%-80%, can save coal 10%-15%, so as to achieve the intention of reducing greenhouse gas emissions, which has been universally recognized by the country and users.
The purpose of boiler economic operation is to reduce coal consumption, save energy, and minimize the overall operating cost of the boiler. There are many factors that affect the economic operation of the boiler, including technical problems and management problems. Most of the boilers in my country are small and medium-sized, and the degree of mechanization is low. The average efficiency is only about 60%, which is generally 10% lower than that of developed countries. The energy saving potential is huge.
What types of boiler products are there?
There are many types of boiler products, which can be divided into different types according to boiler body type, fuel, pressure, combustion method, etc., but generally they are subdivided according to the type of fuel, and are divided into coal-fired boilers, oil-fired boilers, and gas-fired boilers according to the types of fuels used. Boiler etc. The boiler parameters of different fuel types are different, such as boiler size, boiler weight, thermal efficiency, fuel consumption, outlet water temperature (steam temperature), etc.
The most important parameter for boiler products is the thermal efficiency of the boiler. The thermal efficiency of the boiler refers to the percentage of the useful heat generated by the incineration of the boiler fuel and the total heat, that is, the greater the useful heat, the greater the thermal efficiency of the boiler. High, on the contrary, the smaller the effective heat, the lower the thermal efficiency of the boiler. The level of thermal efficiency directly affects the fuel consumption, working time and operating cost of the boiler, so the thermal efficiency of the boiler is particularly important.
The improvement of boiler thermal efficiency is only attributed to one of the boiler energy-saving skills. What energy-saving skills are there for boilers?
1. Boiler descaling technology
The boiler will appear scale after long-term combustion. The increase of boiler scale will affect the heating area of the boiler. The reduction of the heating area will increase fuel consumption, increase operating costs, and cause the boiler to explode. Therefore, we can reduce the scale content by using boiler descaling technology to improve boiler energy saving.
2. Boiler renovation technology
Because the thermal efficiency of different types of boiler products is different, we can save energy through boiler transformation technology, such as coal-fired boiler transformation gas boiler or gas boiler burner transformation technology can achieve the effect of boiler energy saving.
3. New environmentally friendly fuel technology
For boiler products of different fuel types, the calorific value of their fuel is certain, so we can use fuel technology to carry out energy-saving transformations, such as the use of new chemical fuels with low pollution and high calorific value, which can not only reduce pollution but also increase calorific value , Reduce operating costs, so as to achieve energy-saving effects.
4. Condensed flue gas recovery technology
When the boiler is burning, the flue gas will be discharged into the atmosphere through the chimney, and because the flue gas contains heat, this will cause a waste of heat, and the condensing technology is to use the condensing device to recycle the heat in the flue gas. , This will not only reduce pollution but also save energy.
This horizontal fuel-gas integrated condensing steam boiler of Xinli Boiler adopts boiler energy saving technology to achieve the purpose of boiler thermal efficiency, which is as high as 104%.
